@KittyCat92,
Your mother seems to be codependent ... she should really talk with a therapist to determine what her issues are.
This is your life and I applaud you for living it despite your mother's upset with it. Zoom, FaceTime, WhatsApp - there are ways to see each other while conversing.
All you can do in the meantime is nod, agree, say "I know" a lot and keep doing what you're doing
